Weight Increment Increasing and Reducing System

Abstract

An exercise machine including a weight stack composed of a plurality of separate weights; a lifting bar that extrudes through the weight stack of exercise machine disposed for movement within the weight stack where; a selector pin extendable from within a selected weight plate of the weight stack for removably securing a portion of the weight stack to the lifting bar, whereby the total weight carried by the lifting bar is determined by the portion of the weight stack removably secured to the lifting bar by the selector pin; a series of affixed pulleys of different sizes, and different cable or belt routing is disposed.

What is claimed is: 
     
         1 . An exercise machine comprising:
 a weight stack composed of a plurality of separate weight plates;   a lifting bar disposed for movement within said weight stack;   a selector pin extendable from within a selected weight plate of the weight stack for removably securing a portion of the weight stack to the lifting bar, whereby the total weight carried by the lifting bar is determined by the portion of the weight stack removably secured to the lifting bar by the selector pin;   a series of affixed pulleys of different sizes, and different cable or belt routing;   
     
     
         2 . The exercise machine of  claim 1 , wherein said weight stack is vertically disposed. 
     
     
         3 . The exercise machine of  claim 1 , wherein said weight stack is disposed at an angle to the vertical plane. 
     
     
         4 . The exercise machine of  claim 1 , wherein said lifting bar is mechanically secured to a handlebar, whereby movement of said handlebar by a user of said exercise machine moves said lifting bar within said weight stack 
     
     
         5 . The exercise machine of  claim 4 , wherein said lifting bar is mechanically secured to said handlebar by a cable and pulley system 
     
     
         6 . The exercise machine of  claim 1 , wherein said Weight Increment Increasing and Reducing System is secured to said weight machine; 
     
     
         7 . The exercise machine of  claim 6 , wherein said Weight Increment Increasing and Reducing System is mechanically secured to said handlebar by a cable; 
     
     
         8 . The exercise machine of  claim 6 , wherein said Weight Increment Increasing and Reducing System is mechanically secured by a second cable to said lifting bar; 
     
     
         9 . The exercise machine of  claim 6 , wherein said Weight Increment Increasing and Reducing System consists of a dual pulley system, a larger sized pulley affixed to a smaller size pulley, or different variations of pulley sizes/diameters; 
     
     
         10 . The exercise machine of  claim 6 , wherein said Weight Increment Increasing and Reducing System comprises of a dual pulley system, a larger sized pulley affixed to a smaller size pulley and an additional size pulley/coupling that overlaps one of the affixed pulleys within the dual pulley system, wherein the additional size pulley/coupling can be of various pulley/coupling sizes/diameters; 
     
     
         11 . The exercise machine of  claim 6 , wherein said means for moving pulley/coupling to overlap one of the affixed pulleys within the dual pulley system comprises a hand pusher controlled by the user, wherein different variations of said hand pusher is capable of being operated to move overlapping said pulley/coupling; 
     
     
         12 . The exercise machine of  claim 6 , wherein one of the affixed pulleys of said dual pulley system is pre-wound with a cable or belt and the other end of the cable or belt is connected to the handlebar, and the second affixed pulley of said dual pulley system is connected to a second cable or belt on one side with the other side connected to the lifting bar.
